MD 1860 CONCERNING SEVERE THUNDERSTORM WATCH 620... FOR PARTS OF SOUTHERN SOUTH DAKOTA...AND ADJACENT NORTHERN NEBRASKA
Mesoscale Discussion 1860 NWS Storm Prediction Center Norman OK 0949 PM CDT Sun Aug 25 2019 Areas affected...parts of southern South Dakota...and adjacent northern Nebraska Concerning...Severe Thunderstorm Watch 620... Valid 260249Z - 260445Z The severe weather threat for Severe Thunderstorm Watch 620 continues. SUMMARY...Some severe risk continues across portions of South Dakota, in and near WW 620. With storms -- and possibly some severe risk -- likely to spread southeastward into northern Nebraska with time, some need for a new WW south of the existing watch could arise. DISCUSSION...Latest radar loop shows a band of storms -- with embedded stronger cells -- crossing eastern North Dakota and central South Dakota, through remaining portions of WW 619. These storms are gradually moving into a less unstable environment with eastward extent, and should gradually diminish. Meanwhile, a fast-moving cluster of cells continues moving across southwest South Dakota, and is likely producing strong wind gusts and possibly hail. As these storms continue moving southeastward and encounter a more unstable airmass over northern parts of the Nebraska Panhandle, some expansion/intensification of this convection is expected. Progression of these storms south of WW 620 into the next hour or so may require new WW issuance across parts of Nebraska. ..Goss.. 08/26/2019 ...Please see www.spc.noaa.gov for graphic product...

This fire is burning on BLM-managed public lands about 10 miles northeast of Susanville, Calif. No structures are threatened. Change in acreage from earlier reports is due to more accurate

Keller, WA- The Williams Flats Fire started on August 2, 2019 after a band of early morning thunderstorms with lightning moved across the eastern portion of the Colville Indian Reservation. The fire is burning south of Silver Creek Road, within the designated Game Reserve. Roads have been closed to this area at Kuehne Road and Canteen Creek Roads and plus other roads which could access the fire area. This is for firefighter and public safety. Steep slopes, limited access and primitive roads conditions have hampered containment efforts.The public is advised to stay clear of closure areas due to firefighting equipment moving through the area.Northeast Washington Interagency Incident Management Team 2 assumed command of the incident August 15th.

SPC 0100Z Day 1 Outlook
Day 1 Convective Outlook NWS Storm Prediction Center Norman OK 0733 PM CDT Sun Aug 25 2019 Valid 260100Z - 261200Z ...THERE IS A SLIGHT RISK OF SEVERE THUNDERSTORMS FOR THE CENTRAL DAKOTAS ARCING INTO NORTHEAST WYOMING... ...SUMMARY... Thunderstorms with isolated large hail and severe gusts are expected over the central Dakotas arcing westward into northeast Wyoming this evening. ...Northern Great Plains... Water-vapor imagery this evening shows an amplifying mid-level trough over MT which is forecast to reach the Dakotas late tonight. A couple of strong to severe thunderstorm clusters are over the central Dakotas this evening near a pre-frontal surface trough and other intensifying severe storms are located near a cold frontal segment over northeast WY. Both boundaries are forecast to move southeast tonight. The 00z North Platte, NE raob sampled a moisture-rich boundary layer (13 g/kg lowest 100mb mean mixing ratio) which likely extends into the central Dakotas. Moderate instability and the increasing westerly flow moving east through the base of the shortwave trough, will combine to favor storm organization and intensity through the evening. A longer-term risk for severe storms will probably occur with the northeast WY storms as they move east-southeastward into western SD and towards far northern NE on the leading edge of stronger mid-level forcing for ascent. Large hail and severe gusts are the primary risks with the stronger storms. A gradual diminishing in storm coverage and intensity are expected by the late overnight hours. ..Smith.. 08/26/2019 Read more
